I agree with putting the cub on a shelf.
Go to your local flying field and get with an instructor. Let him teach you all the things you need to know from field rules to tuning an engine to flying. Not mention safety. If you don't know where a field is go to the AMA website.
A sim is a great tool and you will progress quicker with a sim. But a sim can enforce bad habits.
Good luck and welcome to the addiction.
